Dear Investor:

Thank you for reviewing this annual report for the period ended August 31, 2023. Annual reports help convey important information about fund returns, including market factors that affected performance. For additional investment insights, please visit avantisinvestors.com.

Stocks Rebounded, Bonds Struggled

Asset class returns, particularly for U.S. and global stocks, improved dramatically compared with the previous fiscal year. The bounce back occurred despite ongoing volatility, rising interest rates and Fitch Ratings’ first-ever downgrade of U.S. debt.

Investor expectations for the Federal Reserve (Fed) to conclude its rate-hike campaign partly fueled the optimism. Inflation’s steady slowdown, mounting recession worries and a series of U.S. regional bank failures prompted investors to regularly recalibrate their monetary policy outlooks. However, with inflation still higher than central bank targets, the Fed and its developed markets peers continued to raise interest rates.

After pausing in June, the Fed resumed its tightening campaign in July, raising rates to a range of 5.25% to 5.5%, a 22-year high. Citing still-higher-than-target inflation and still-strong economic data, policymakers left their future policy options open. Inflation remained even higher in the eurozone and the U.K., prompting central bankers there to steadily raise interest rates. Government bond yields soared, including the benchmark 10-year Treasury yield, which surged to a 16-year high late in the period.

Despite the inflation and rate backdrops, better-than-expected corporate earnings helped the S&P 500 Index return 15.94% for the 12-month period. Non-U.S. developed markets stocks delivered modestly higher returns, while emerging markets stocks gained only 1.25%. Meanwhile, amid elevated inflation and sharply higher Treasury yields, most U.S. bond and other rate-sensitive sectors declined, though not as much as in the prior fiscal year. Exceptions included corporate and municipal bonds, which delivered modest gains.

Remaining Diligent in Uncertain Times

We expect market volatility to linger as investors navigate a complex environment of persistent inflation, tighter financial conditions, banking industry turbulence and recession risk. In addition, increasingly tense geopolitical considerations complicate the market backdrop.

We appreciate your confidence in us during these extraordinary times. American Century Investments has a long history of helping clients weather unpredictable and volatile markets, and we’re confident we will continue to meet today’s challenges.

Sincerely,

Fund Strategy

Avantis All Equity Markets ETF is a fund of funds that seeks long-term capital appreciation by investing in other Avantis ETFs. These underlying funds represent a broadly diversified basket of equity securities and seek to overweight securities expected to have higher returns or better risk characteristics than a passive, market-capitalization weighted index.

Collectively, the underlying funds seek securities of companies that they expect to have higher returns. They place an enhanced emphasis on securities of companies with smaller market capitalizations and securities of companies with higher profitability and value characteristics. Conversely, the underlying funds collectively seek to underweight or exclude securities they expect to have lower returns. This includes securities of large companies with lower levels of profitability and higher prices relative to their book values or other financial metrics.

The fund is an actively managed exchange-traded fund (ETF) that does not seek to replicate the performance of a specified index. Under normal market conditions, the fund will invest at least 80% of its assets in equity ETFs. The managers will strategically allocate to the underlying funds across geographies and investment styles to achieve the desired allocation. The U.S. versus non-U.S. allocations will be predicated on each region’s relative market capitalization with a home bias toward the U.S. The portfolio managers regularly review the fund’s allocations to determine whether rebalancing is appropriate. To better balance risks in changing market environments and control costs and tax realizations, the portfolio managers may modestly reallocate within asset class target ranges. This may occur when prevailing market conditions and relative performance of certain underlying strategies lead to deviations from the targets.

Performance Review

For the period from the fund’s inception on September 27, 2022, through August 31, 2023, Avantis All Equity Markets ETF returned 24.02%* on a market price basis. On a net asset value (NAV) basis, the fund returned 24.04%. NAV and market price returns reflect fees and operating expenses, while index returns do not.

The fund underperformed the total world stock market, as measured by the MSCI ACWI IMI Index, which returned 24.29% for the reporting period. The index is an unmanaged index generally representative of the performance of large-, mid- and small-cap stocks in developed and emerging markets.

The fund’s underperformance versus the index was largely due to the fund’s collective underweight versus the index in mega- and large-cap stocks, which generally outperformed their smaller peers.

















*Total returns for periods less than one year are not annualized. Fund returns would have been lower if a portion of the fees had not been waived.

Portfolio Commentary

Fund Strategy

Avantis Moderate Allocation ETF is a fund of funds that seeks long-term capital appreciation by investing in other Avantis equity and fixed income ETFs. These underlying funds represent a broadly diversified basket of stocks and bonds and seek to overweight securities expected to have higher returns or better risk characteristics than a passive, market-capitalization weighted index.

To identify securities with higher expected returns, the underlying equity funds collectively emphasize securities of companies with smaller market capitalizations and securities of companies it defines as high profitability or value companies. Conversely, the underlying equity funds collectively seek to underweight or exclude securities they expect to have lower returns. This includes securities of large companies with lower levels of profitability and higher prices relative to their book values or other financial metrics. The portfolio managers of the underlying fixed-income funds use factors such as industry sector, credit rating, duration, country and currency to categorize fixed-income securities into component groups. They calculate the expected return of securities in each component group by using information embedded in current yields and other valuation metrics.

The fund is an actively managed exchange-traded fund (ETF) that does not seek to replicate the performance of a specified index. The portfolio managers will allocate to the underlying funds across geographies and investment styles to achieve the desired allocation. Among equities, the U.S. versus non-U.S. allocations across geographies depend on each region’s relative market capitalization with a home bias toward the U.S. The portfolio managers regularly review the fund’s allocations to determine whether rebalancing is appropriate. To better balance risks in changing market environments and control costs and tax realizations, the portfolio managers may modestly reallocate within target asset class ranges. This may occur when prevailing market conditions and relative performance of certain underlying strategies lead to deviations from the targets.

Performance Review

For the period from the fund’s inception on June 27, 2023, through August 31, 2023, Avantis Moderate Allocation ETF returned 2.13%* on a market price basis. On a net asset value (NAV) basis, the fund returned 2.09%. NAV and market price returns reflect fees and operating expenses, while index returns do not.

The fund outperformed the broad world stock and U.S. bond markets, as measured by the 65% MSCI ACWI Investable Market Index (IMI)/35% Bloomberg U.S. Aggregate Government/Credit 1-5 Year Index, which returned 1.67% during the period. The index is an unmanaged index generally representative of the broad performance of developed and emerging markets stocks, including all capitalization categories, and U.S. investment-grade bonds with maturities of one to five years.

The fund’s relative outperformance was largely due to the fund’s collective overweight versus the index in equity securities from companies with the highest profitability and book-to-market characteristics, which outperformed. A corresponding underweight in companies with the lowest profitability and book-to-market characteristics, which underperformed, also aided relative results.

Shareholder Fee Examples

Fund shareholders may incur two types of costs: (1) transaction costs, including brokerage commissions paid on purchases and sales of fund shares; and (2) ongoing costs, including management fees and other fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in your fund and to compare these costs with the ongoing cost of investing in other funds.

The example is based on an investment of $1,000 made at the beginning of the period and held for the entire period from March 1, 2023 to August 31, 2023 (except as noted).

Actual Expenses

The table provides information about actual account values and actual expenses for each fund. You may use the information, together with the amount you invested, to estimate the expenses that you paid over the period. First, identify the fund you own. Then simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number under the heading “Expenses Paid During Period” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The table also provides information about hypothetical account values and hypothetical expenses based on the actual expense ratio of your fund and an assumed rate of return of 5% per year before expenses, which is not the actual return of a fund. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in your fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as brokerage commissions paid on purchases and sales of fund shares. Therefore, the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

Notes to Financial Statements

AUGUST 31, 2023

1. Organization

American Century ETF Trust (the trust) was registered as a Delaware statutory trust in 2017 and is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company. Avantis All Equity Markets ETF, Avantis All Equity Markets Value ETF, Avantis All International Markets Equity ETF, Avantis All International Markets Value ETF and Avantis Moderate Allocation ETF (collectively, the funds) are five funds in a series issued by the trust. The funds each operate as a “fund of funds,” meaning substantially all of the funds' assets will be invested in a combination of Avantis exchange-traded funds (the underlying funds). Avantis All Equity Markets ETF, Avantis All Equity Markets Value ETF, Avantis All International Markets Equity ETF and Avantis All International Markets Value ETF underlying funds represent a broadly diversified basket of equity securities. Avantis Moderate Allocation ETF underlying funds represent a broadly diversified basket of equity and fixed income securities. The funds will assume the risks associated with the underlying funds. Additional information and attributes of each underlying fund are available at avantisinvestors.com. Each of the funds' investment objective is to seek long-term capital appreciation. Shares of the funds are listed for trading on the NYSE Arca, Inc. Avantis All Equity Markets ETF incepted on September 27, 2022. Avantis All Equity Markets Value ETF, Avantis All International Markets Equity ETF, Avantis All International Markets Value ETF and Avantis Moderate Allocation ETF incepted on June 27, 2023.

2. Significant Accounting Policies

The following is a summary of significant accounting policies consistently followed by the funds in preparation of their financial statements. Each fund is an investment company and follows accounting and reporting guidance in accordance with accounting principles generally accepted in the United States of America. This may require management to make certain estimates and assumptions at the date of the financial statements. Actual results could differ from these estimates. Management evaluated the impact of events or transactions occurring through the date the financial statements were issued that would merit recognition or disclosure.

Investment Valuations — The funds determine the fair value of their investments and compute their net asset value (NAV) per share at the close of regular trading (usually 4 p.m. Eastern time) on the New York Stock Exchange (NYSE) on each day the NYSE is open. The value of investments of the funds are determined by American Century Investment Management, Inc. (ACIM) (the investment advisor), as the valuation designee, pursuant to its valuation policies and procedures. The Board of Trustees oversees the valuation designee and reviews its valuation policies and procedures at least annually. 

Open-end management investment companies are valued at the reported NAV. Exchange-traded funds are listed or traded on a domestic securities exchange and are valued at the last reported sales price or at the official closing price as provided by the exchange.

Security Transactions — Security transactions are accounted for as of the trade date. Net realized gains and losses are determined on the identified cost basis, which is also used for federal income tax purposes.

Investment Income — Income and capital gain distributions, if any, from the underlying funds are recorded as of the ex-dividend date. Long-term capital gain distributions, if any, from the underlying funds are a component of net realized gain (loss). Interest income is recorded on the accrual basis and includes accretion of discounts and amortization of premiums. Securities lending income is net of fees and rebates earned by the lending agent for its services.

Income Tax Status — It is each fund's policy to distribute substantially all net investment income and net realized gains to shareholders and to otherwise qualify as a regulated investment company under provisions of the Internal Revenue Code. Accordingly, no provision has been made for income taxes. The funds file U.S. federal, state, local and non-U.S. tax returns as applicable. The funds' tax returns are subject to examination by the relevant taxing authority until expiration of the applicable statute of limitations, which is generally three years from the date of filing but can be longer in certain jurisdictions. At this time, management believes there are no uncertain tax positions which, based on their technical merit, would not be sustained upon examination and for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months.
34


Distributions to Shareholders — Distributions from net investment income, if any, are generally declared and paid semiannually. Distributions from net realized gains, if any, are generally declared and paid annually.

Indemnifications — Under the trust’s organizational documents, its officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the funds. In addition, in the normal course of business, the funds enter into contracts that provide general indemnifications. The maximum exposure under these arrangements is unknown as this would involve future claims that may be made against a fund. The risk of material loss from such claims is considered by management to be remote.

Securities Lending — Securities are lent to qualified financial institutions and brokers. State Street Bank & Trust Co. serves as securities lending agent to the funds pursuant to a Securities Lending Agreement. The lending of securities exposes the funds to risks such as: the borrowers may fail to return the loaned securities, the borrowers may not be able to provide additional collateral, the funds may experience delays in recovery of the loaned securities or delays in access to collateral, or the funds may experience losses related to the investment collateral. To minimize certain risks, loan counterparties pledge collateral in the form of cash and/or securities. The lending agent has agreed to indemnify the funds in the case of default of any securities borrowed. Cash collateral received is invested in the State Street Navigator Securities Lending Government Money Market Portfolio, a money market mutual fund registered under the 1940 Act. The loans may also be secured by U.S. government securities in an amount at least equal to the market value of the securities loaned, plus accrued interest and dividends, determined on a daily basis and adjusted accordingly. By lending securities, the funds seek to increase their net investment income through the receipt of interest and fees. Such income is reflected separately within the Statements of Operations. The value of loaned securities and related collateral outstanding at period end, if any, are shown on a gross basis within the Schedules of Investments and Statements of Assets and Liabilities.

3. Fees and Transactions with Related Parties

Certain officers and trustees of the trust are also officers and/or directors of American Century Companies, Inc. (ACC). The trust's investment advisor, ACIM, and the trust’s administrator, American Century Services, LLC, are wholly owned, directly or indirectly, by ACC.

Management Fees — The trust has entered into a management agreement with ACIM, under which ACIM provides the funds with investment advisory and management services in exchange for a single, unified management fee (the fee). The agreement provides that ACIM will pay all expenses of managing and operating the funds, except brokerage and other transaction fees and expenses relating to the acquisition and disposition of portfolio securities, acquired fund fees and expenses, interest, taxes, litigation expenses, extraordinary expenses and, in the case of certain funds, fees and expenses of the independent trustees (including legal counsel fees). The fee is computed and accrued daily based on the daily net assets of each fund and paid monthly in arrears. During the period ended August 31, 2023, the investment advisor agreed to waive 0.02% of each fund's management fee. The investment advisor expects this waiver to continue until June 21, 2024 for Avantis All Equity Markets Value ETF, Avantis All International Markets Equity ETF, Avantis All International Markets Value ETF and Avantis Moderate Allocation ETF and July 31, 2024 for Avantis All Equity Markets ETF and cannot terminate it prior to such date without the approval of the Board of Trustees.

The annual management fee and the effective annual management fee after waiver for each fund for the period ended August 31, 2023 are as follows:
Effective Annual Management Fee
Annual Management Fee
After Waiver
Avantis All Equity Markets ETF 0.05% 0.03%
Avantis All Equity Markets Value ETF 0.05% 0.03%
Avantis All International Markets Equity ETF 0.05% 0.03%
Avantis All International Markets Value ETF 0.05% 0.03%
Avantis Moderate Allocation ETF 0.05% 0.03%

Trustees' Fees and Expenses — The Board of Trustees is responsible for overseeing the investment advisor's management and operations of the funds. The trustees receive detailed information about the funds and their investment advisor regularly throughout the year, and meet at least quarterly with management of the investment advisor to review reports about fund operations.

Acquired Fund Fees and Expenses — Each fund will indirectly realize its pro rata share of the fees and expenses of the underlying funds in which it invests. These fees and expenses are already reflected in the valuation of the underlying funds.

(2)June 27, 2023 (fund inception) through August 31, 2023.

5. Capital Share Transactions

Each fund’s shares may only be bought and sold in a secondary market through a broker-dealer at a market price. Because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). Each fund issues and redeems shares at their NAV only in aggregations of a specified number of shares (a creation unit) generally in exchange for a designated portfolio of securities and/or cash (including any portion of such securities for which cash may be substituted). Authorized participants may be required to pay an additional variable charge to cover certain brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to the execution of trades resulting from creation unit transactions. Such variable charges, if any, are included in other capital within the Statements of Changes in Net Assets.

6. Fair Value Measurements

The funds' investment valuation process is based on several considerations and may use multiple inputs to determine the fair value of the investments held by the funds. In conformity with accounting principles generally accepted in the United States of America, the inputs used to determine a valuation are classified into three broad levels. 

Level 1 valuation inputs consist of unadjusted quoted prices in an active market for identical investments.

Level 2 valuation inputs consist of direct or indirect observable market data (including quoted prices for comparable investments, evaluations of subsequent market events, interest rates, prepayment speeds, credit risk, etc.). These inputs also consist of quoted prices for identical investments initially expressed in local currencies that are adjusted through translation into U.S. dollars. 

Level 3 valuation inputs consist of unobservable data (including a fund’s own assumptions).

36


The level classification is based on the lowest level input that is significant to the fair valuation measurement. The valuation inputs are not necessarily an indication of the risks associated with investing in these securities or other financial instruments.

As of period end, the funds' investment securities were classified as Level 1. The Schedules of Investments provide additional information on the funds' portfolio holdings.

7. Federal Tax Information

The tax character of distributions paid during the period ended August 31, 2023 were as follows:
2023
Distributions Paid From:
Ordinary
Income
Long-term
Capital Gains
Avantis All Equity Markets ETF(1)
$ 2,251,161
Avantis All Equity Markets Value ETF(2)
Avantis All International Markets Equity ETF(2)
Avantis All International Markets Value ETF(2)
Avantis Moderate Allocation ETF(2)
(1)September 27, 2022 (fund inception) through August 31, 2023.
(2)June 27, 2023 (fund inception) through August 31, 2023.

The book-basis character of distributions made during the year from net investment income or net realized gains may differ from their ultimate characterization for federal income tax purposes. These differences reflect the differing character of certain income items and net realized gains and losses for financial statement and tax purposes, and may result in reclassification among certain capital accounts on the financial statements.

The reclassifications, which are primarily due to in kind transactions and net operating losses, were as follows:
Avantis All Equity Markets ETF Avantis All Equity Markets Value ETF Avantis All International Markets Equity ETF Avantis All International Markets Value ETF Avantis Moderate Allocation ETF
Capital paid in $ 534,484  $ (508) $ (3,948) $ (5,646) — 
Distributable earnings (loss) $ (534,484) $ 508  $ 3,948  $ 5,646  — 


37


As of period end, the federal tax cost of investments and the components of distributable earnings on a tax-basis were as follows:
Avantis All Equity Markets ETF Avantis All Equity Markets Value ETF Avantis All International Markets Equity ETF Avantis All International Markets Value ETF Avantis Moderate Allocation ETF
Federal tax cost of investments $ 206,466,958  $ 18,322,967  $ 648,433  $ 382,622  $ 2,057,962 
Gross tax appreciation of investments $ 13,499,914  $ 107,864  $ 93  $ 3,651  $ 7,383 
Gross tax depreciation of investments (170,597) (28,248) (8,716) —  (2,603)
Net tax appreciation (depreciation) of investments $ 13,329,317  $ 79,616  $ (8,623) $ 3,651  $ 4,780 
Undistributed ordinary income $ 7,027  —  —  —  $ 1,022 
Accumulated short-term capital losses $ (78,582) —  —  —  — 
The difference between book-basis and tax-basis unrealized appreciation (depreciation) is attributable primarily to the tax deferral of losses on wash sales for Avantis All Equity Markets ETF. The cost of investments for federal income tax purposes was the same as the cost for financial reporting purposes for Avantis All Equity Markets Value ETF, Avantis All International Markets Equity ETF, Avantis All International Markets Value ETF and Avantis Moderate Allocation ETF.

Accumulated capital losses represent net capital loss carryovers that may be used to offset future realized capital gains for federal income tax purposes. The capital loss carryovers may be carried forward for an unlimited period. Future capital loss carryover utilization in any given year may be subject to Internal Revenue Code limitations.

8. Investments in Underlying Funds

The funds do not invest in the underlying funds for the purpose of exercising management or control; however, investments by the funds within their investment strategies may represent a significant portion of the underlying funds’ net assets. As of period end, All Equity Markets ETF owned 55% of the shares of
Avantis International Small Cap Equity ETF.

9. Risk Factors

The value of the funds’ shares will go up and down based on the performance of the underlying funds in which they invest. The value of the underlying funds’ shares will, in turn, fluctuate based on the performance of the securities they own and other factors generally affecting the securities market. Market risks, including political, regulatory, economic and social developments, can affect the value of the funds’ investments. Natural disasters, public health emergencies, war, terrorism and other unforeseeable events may lead to increased market volatility and may have adverse long-term effects on world economies and markets generally.

Basis for Opinion

These financial statements and financial highlights are the responsibility of the Funds’ management. Our responsibility is to express an opinion on the Funds’ financial statements and financial highlights based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Funds in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement, whether due to error or fraud. The Funds are not required to have, nor were we engaged to perform, an audit of their internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Funds’ internal control over financial reporting. Accordingly, we express no such opinion.


47


Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements and financial highlights. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights. Our procedures included confirmation of securities owned as of August 31, 2023, by correspondence with the custodian and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

Management

The Board of Trustees
The individuals listed below serve as trustees of the funds. Each trustee will continue to serve in this capacity until death, retirement, resignation or removal from office. The board has adopted a mandatory retirement age for trustees who are not “interested persons,” as that term is defined in the Investment Company Act (independent trustees). Trustees who are not also officers of the trust shall retire on December 31st of the year in which they reach their 75th birthday.
Jonathan S. Thomas is an “interested person” because he currently serves as President and Chief Executive Officer of American Century Companies, Inc. (ACC), the parent company of American Century Investment Management, Inc. (ACIM or the advisor). The other trustees are independent.

Approval of Management Agreements
Avantis All Equity Markets ETF
At a meeting held on June 21, 2023, the Fund’s Board of Trustees (the "Board") unanimously approved the renewal of the management agreement pursuant to which American Century Investment Management, Inc. (the “Advisor”) acts as the investment advisor for the Fund. Under the Investment Company Act of 1940 (the “Investment Company Act”), contracts for investment advisory services are required to be reviewed, evaluated, and approved by a majority of a fund’s Trustees, including a majority of the independent Trustees.

Prior to its consideration of the renewal of the management agreement, the Trustees requested and reviewed extensive data and information compiled by the Advisor and certain independent data providers concerning the Fund. This review was in addition to the oversight and evaluation undertaken by the Board and its Audit Committee on a continual basis and the information received was supplemental to the extensive information that the Board and its Audit Committee receive and consider over time.

In connection with its consideration of the renewal of the management agreement, the Board’s review and evaluation of the services provided by the Advisor included, but was not limited to

the nature, extent, and quality of investment management, shareholder services, distribution services, and other services provided to the Fund;
the wide range of programs and services the Advisor and other service providers provide to the Fund and its shareholders on a routine and non-routine basis;
the Fund’s investment performance compared to appropriate benchmarks and/or peer groups of other funds with similar investment objectives and strategies;
the cost of owning the Fund compared to the cost of owning similarly-managed funds;
the Advisor’s compliance policies, procedures, and regulatory experience and those of certain other service providers;
the Advisor’s strategic plans, generally, and with respect to areas of heightened regulatory interest in the mutual fund industry and certain recent geopolitical and other issues;
the Advisor’s business continuity plans, vendor management practices, and information security practices;
the cost of services provided to the Fund, the profitability of the Fund to the Advisor, and the Advisor’s financial results of operation;
possible economies of scale associated with the Advisor’s management of the Fund;
any collateral benefits derived by the Advisor from the management of the Fund;
fees and expenses associated with any investment by the Fund in other funds;
payments to intermediaries by the Fund and the Advisor and services provided by intermediaries in connection therewith; and
services provided and charges to the Advisor’s other investment management clients.

The independent Trustees met separately in private sessions to discuss the renewal and to review and discuss the information provided in response to their request. The independent Trustees also held active discussions with the Advisor regarding the renewal of the management agreement. The independent Trustees had the benefit of the advice of their independent counsel throughout the process.

Factors Considered

The Trustees considered all of the information provided by the Advisor, the independent data providers, and independent counsel in connection with the approval. They determined that the information was sufficient for them to evaluate the management agreement for the Fund. In connection with their review, the Trustees did not identify any single factor as being all-important or controlling, and each Trustee may have attributed different levels of importance to different factors.
51


In deciding to renew the management agreement, the Board based its decision on a number of factors, including without limitation the following:

Nature, Extent and Quality of Services — Generally. Under the Fund’s management agreement, the Advisor is responsible for providing or arranging for all services necessary for the operation of the Fund. The Board noted that the Advisor provides or arranges at its own expense a wide variety of services which include the following:

constructing and designing the Fund
portfolio research and security selection
initial capitalization/funding
securities trading
Fund administration
custody of Fund assets
daily valuation of the Fund’s portfolio
liquidity monitoring and management
risk management, including information security
shareholder servicing and transfer agency, including shareholder confirmations, recordkeeping, and communications
legal services (except the independent Trustees’ counsel)
regulatory and portfolio compliance
financial reporting
marketing and distribution (except amounts paid by the Fund under Rule 12b-1 plans)

Investment Management Services. The nature of the investment management services provided to the Fund is quite complex and allows Fund shareholders access to professional money management, instant diversification of their investments, and liquidity. In evaluating investment performance, the Board expects the Advisor to manage the Fund in accordance with its investment objectives and principal investment strategies. Further, the Trustees recognize that the Advisor has an obligation to monitor trading activities, and in particular to seek the best execution of fund trades, and to evaluate the use of and payment for research. In providing these services, the Advisor utilizes teams of investment professionals who require extensive information technology, research, training, compliance, and other systems to conduct their business. The Board provides oversight of the investment performance process. It regularly reviews investment performance information for the Fund, together with comparative information for appropriate benchmarks over different time horizons. The Trustees also review investment performance information during the management agreement renewal process. If performance concerns are identified, the Board discusses with the Advisor the reasons for such results and any actions being taken to improve performance. The Board found the investment management services provided by the Advisor to the Fund to be satisfactory and consistent with the management agreement.

Shareholder and Other Services. Under the management agreement, the Advisor provides or arranges for a comprehensive package of services to the Fund. The Board, directly and through its Audit Committee, regularly reviews reports and evaluations of such services at its regular meetings. These reports include, but are not limited to, information regarding the operational efficiency and accuracy of the shareholder and transfer agency services provided, staffing levels, shareholder satisfaction, technology support (including information security), new products and services offered to Fund shareholders, securities trading activities, portfolio valuation services, auditing services, and legal and operational compliance activities. The Board found the services provided by the Advisor to the Fund under the management agreement to be competitive and of high quality.

Costs of Services and Profitability. The Advisor provides detailed information concerning its cost of providing various services to the Fund, its profitability in managing the Fund (pre- and post-distribution), and its financial results of operation. The Trustees have reviewed with the Advisor the methodology used to prepare this financial information. This information is considered in evaluating the Advisor’s financial condition, its ability to continue to provide services under the management
52


agreement, and the reasonableness of the terms of the current management agreement. The Board concluded that the Advisor’s profits were reasonable in light of the services provided to the Fund.

Ethics. The Board generally considers the Advisor’s commitment to providing quality services to the Fund and to conducting its business ethically. They noted that the Advisor’s practices generally meet or exceed industry best practices.

Economies of Scale. The Board also reviewed information provided by the Advisor regarding the possible existence of economies of scale in connection with the management of the Fund. The Board concluded that economies of scale are difficult to measure and predict with precision, especially on a fund-by-fund basis. The Board concluded that the Advisor is sharing economies of scale, to the extent they exist, through its fee structure and through reinvestment in its business, infrastructure, investment capabilities and initiatives to provide shareholders additional content and services.

Comparison to Other Funds’ Fees. The management agreement provides that the Fund pays the Advisor a single, all-inclusive (or unified) management fee for providing all services necessary for the management and operation of the Fund, other than brokerage and other transaction fees and expenses relating to acquisition and disposition of portfolio securities, acquired fund fees and expenses, taxes, interest, extraordinary expenses, fund litigation expenses, expenses incurred in connection with the provision of shareholder services and distribution services under a plan adopted pursuant to Investment Company Act Rule 12b-1, and, for certain funds, fees and expenses of the Fund’s independent Trustees (including their independent legal counsel). Under the unified fee structure, the Advisor is responsible for providing investment advisory, custody, audit, administrative, compliance, recordkeeping, marketing and shareholder services, or arranging and supervising third parties to provide such services. The Board believes the unified fee structure is a benefit to Fund shareholders because it clearly discloses to shareholders the cost of owning Fund shares, and, since the unified fee cannot be increased without a vote of Fund shareholders, it shifts to the Advisor the risk of increased costs of operating the Fund and provides a direct incentive to minimize administrative inefficiencies. Part of the Board’s analysis of fee levels involves reviewing certain evaluative data compiled by an independent provider comparing the Fund’s unified fee to the total expense ratios of its peers. The unified fee charged to shareholders of the Fund was the lowest of the total expense ratios of the Fund’s peer expense universe and its peer expense group. The Board concluded that the management fee paid by the Fund to the Advisor under its management agreement is reasonable in light of the services provided to the Fund.

Comparison to Fees and Services Provided to Other Clients of the Advisor. The Board also requested and received information from the Advisor concerning the nature of the services, fees, costs, and profitability of its advisory services to funds or other advisory clients managed similarly to the Fund. They observed that these varying types of client accounts require different services and involve different regulatory and entrepreneurial risks than the management of the Fund. The Board analyzed this information and concluded that the fees charged and services provided to the Fund were reasonable by comparison.

Payments to Intermediaries. The Trustees also requested and received a description of payments made to intermediaries by the Fund and the Advisor and services provided in response thereto. These payments could include various payments made by the Fund or the Advisor to different types of intermediaries and recordkeepers for distribution and service activities provided for the Fund. The Trustees reviewed such information and received representations from the Advisor that all such payments by the Advisor were made from the Advisor’s resources and reasonable profits.

Collateral or “Fall-Out” Benefits Derived by the Advisor. The Board considered the possible existence of collateral benefits the Advisor may receive as a result of its relationship with the Fund. They concluded that the Advisor’s primary business is managing funds and it generally does not
53


use fund or shareholder information to generate profits in other lines of business, and therefore does not derive any significant collateral benefits from them. The Board noted that additional assets from other clients may offer the Advisor some benefit from increased leverage with prospective clients, service providers, and counterparties. The Board also determined that the Advisor is able to provide investment management services to certain clients other than the Fund, at least in part, due to its existing infrastructure built to serve the fund complex. The Board concluded that appropriate allocation methodologies had been employed to assign resources and the cost of those resources to these other clients.

Existing Relationship. The Board also considered whether there was any reason for not continuing the existing arrangement with the Advisor. In this regard, the Board was mindful of the potential disruptions of the Fund’s operations and various risks, uncertainties, and other effects that could occur as a result of a decision not to continue such relationship. In particular, the Board recognized that most shareholders have invested in the Fund on the strength of the Advisor’s industry standing and reputation and in the expectation that the Advisor will have a continuing role in providing advisory services to the Fund.

Conclusion of the Trustees. As a result of this process, the Board, including all of the independent Trustees, taking into account all of the factors discussed above and the information provided by the Advisor and others in connection with its review and received over time, determined that the terms of the management agreement are fair and reasonable and that the management fee charged to the Fund is fair in light of the services provided and that the investment management agreement between the Fund and the Advisor should be renewed for an additional one-year period.

At a meeting held on March 15, 2023, the Funds’ Board of Trustees (the "Board") unanimously approved the initial management agreement pursuant to which American Century Investment Management, Inc. (the “Advisor”) acts as the investment advisor for the Avantis All Equity Markets Value ETF, Avantis All International Markets Equity ETF, Avantis All International Markets Value ETF, and Avantis Moderate Allocation ETF (collectively the "New Funds"). Under the Investment Company Act of 1940, new contracts for investment advisory services are required to be approved by a majority of a fund’s independent Trustees.

In advance of the Board’s consideration, the Advisor provided information concerning the New Funds. The materials reviewed and the discussions held detailed the investment objective and strategy proposed to be utilized by the Advisor, the New Funds’ characteristics and key attributes, the rationale for launching the New Funds, the experience of the staff designated to manage the New Funds, the proposed pricing, and the markets in which the New Funds would be sold. The information considered and the discussions held included, but were not limited to:

the nature, extent, and quality of investment management and other services to be provided to the New Funds;
the wide range of other programs and services the Advisor would provide to each New Fund and its shareholders on a routine and non-routine basis;
each New Fund’s proposed investment objective and strategy, including a discussion of its anticipated investment performance and proposed benchmark;
the cost of owning each New Fund compared to the cost of owning similarly-managed funds;
the Advisor’s compliance policies, procedures, and regulatory experience; and
any collateral benefits derived by the Advisor from the management of the New Funds.

Part of the Board’s analysis of fee levels involves reviewing certain evaluative data compiled by an independent data provider and comparing each New Fund’s fee to the total expense ratio of expected peer funds. The annual management fees charged to shareholders of each of the New Funds were anticipated to be below the median of the total expense ratios of their respective peer universe.

When considering the approval of the management agreement for the New Funds, the independent Trustees considered the entrepreneurial risk that the Advisor assumes in launching a new fund. In particular, they considered the fact that the Advisor will assume a substantial part of the start-up costs of the New Funds and the risk that the New Funds will not grow to a level that will become profitable to the Advisor. The Board considered the position that the New Funds would take in the lineup of the American Century Investments’ family of funds and the benefits to shareholders of existing funds of the broadened product offering. Finally, while not specifically discussed, but important in the decision to approve the management agreement, is the Trustees’ familiarity with the Advisor. A majority of the Board oversees and evaluates on a continuous basis the nature and quality of all services the Advisor performs for other funds within the American Century Investments’ complex. As such, the Trustees have confidence in the Advisor’s integrity and competence in providing services to the New Funds.

The independent Trustees considered all of the information provided by the Advisor and the independent Trustees’ independent counsel in connection with the approval, and evaluated such information for the New Funds. In connection with their review, the Trustees did not identify any single factor as being all-important or controlling, and each Trustee may have attributed different levels of importance to different factors. The independent Trustees concluded that the terms of the management agreement were fair and reasonable and that the management fee to be charged to the New Fund is reasonable in light of the services to be provided and should be approved.

Liquidity Risk Management Program

The Funds have adopted a liquidity risk management program (the “program”). The Funds' Board of Trustees (the "Board") has designated American Century Investment Management, Inc. (“ACIM”) as the administrator of the program. Personnel of ACIM or its affiliates, including members of ACIM’s Investment Oversight Committee who are members of ACIM’s Investment Management and Global Analytics departments, conduct the day-to-day operation of the program pursuant to the program.

Under the program, ACIM manages the Funds' liquidity risk, which is the risk that the Funds could not meet shareholder redemption requests without significant dilution of remaining shareholders’ interests in the Funds. This risk is managed by monitoring the degree of liquidity of the Funds' investments, limiting the amount of the Funds' illiquid investments, and utilizing various risk management tools and facilities available to the Funds for meeting shareholder redemptions, among other means. ACIM’s process of determining the degree of liquidity of certain investments held by the Funds are supported by a third-party liquidity assessment vendor.

The Board reviewed a report prepared by ACIM regarding the operation and effectiveness of the program for the period January 1, 2022 through December 31, 2022. No significant liquidity events impacting the Funds were noted in the report. In addition, ACIM provided its assessment that the program had been effective in managing the Funds' liquidity risk.
